Question

A scooter maintains a pace of 1.45 minutes per mile, with fuel economy of 85 miles per gallon. How many seconds can it travel on 145 mL of fuel under these conditions

Answer 1

281s

Step-by-step explanation:

Given parameters:

Speed of the scooter = 1.45min per mile

Fuel economy of engine = 85miles per gallon

Quantity of fuel = 145mL

Unknown:

Time of travel with the volume of fuel given = ?

Solution:

To solve this problem, we need to find the distance the fuel will last.

Rate of fuel consumption by the engine = 85miles per gallon

Convert 145mL to gallons;

3785.41mL = 1 gallon

145mL will therefore give
`(145)/(3785.41)` = 0.038gallons

So;

Distance covered = 85miles per gallon x 0.038gallons = 3.23miles

From;

Rate of travel =
`(time )/(distance)`

Time = rate of travel x distance = 1.45 minutes per mile x 3.23miles

Time = 4.7min

1 min = 60s

4.7min = 4.7 x 60 = 281s
